How the SL182230 model number is decoded

envelope 150×270×73 mm with a 60.0 mm radial section; every available circumferential space carries a roller because there is no cage C is 820 kN and C0 1160 kN; with a C/C0 ratio of 0.71 the 73 mm-wide full complement concentrates on extreme static and steady radial capacity rather than speed the fatigue load limit Cur is 154 kN, the limiting speed 1,560 r/min and the thermal reference speed 1,130 r/min — full-complement roller-to-roller contact keeps both speeds well below caged cylindrical bearings of the same size the dynamic rating is 5.47 kN per millimetre of the 150 mm bore and 11.23 kN per millimetre of the 73 mm width, figures that explain the use of this bearing in compact, heavily loaded gearbox positions mass is 18.43 kg (18430 g) (0.94 g per mm² of the 270×73 mm envelope); the stiff, thick rings keep raceway deformation low under peak loads 150 mm bore, 270 mm outside diameter: at this size the 1160 kN C0 rating and rigid full-complement pack replace multi-bearing arrangements in compact heavy-duty designs The dimension-series digits place this bearing in the SL18 section of the HR1 plan, giving the 60.0 mm section height between the 150 mm bore and the 270 mm outside diameter In the 270 mm envelope the cageless pack raises C0 to 1160 kN; the trade is the 1,560 r/min limiting speed, set by roller-to-roller sliding rather than by a cage Typical applications include planetary gear bearing positions, construction machinery slewing drives and compact slow-speed agitator drives, where the 270 mm outside diameter and 820 kN dynamic rating match the duty. In planetary gear bearing positions the unit fits a compact 150 mm seat, and in construction machinery slewing drives the 18.43 kg mass is part of the rotor inertia calculation. Designers also specify it for compact slow-speed agitator drives, relying on the 73 mm width and the published 1160 kN static rating. Use the rib structure correctly: SL18/SL1850 give one-direction axial guidance, SL0149 locates both ways and SL0249 floats — pairing two locating bearings on one shaft binds thermal growth. C0 is the number that tempts overload in slow machinery, but fatigue life is still governed by the dynamic C rating and lubricant film.

Selection pitfalls — read before you substitute

• Use the rib structure correctly: SL18/SL1850 give one-direction axial guidance, SL0149 locates both ways and SL0249 floats — pairing two locating bearings on one shaft binds thermal growth.
• C0 is the number that tempts overload in slow machinery, but fatigue life is still governed by the dynamic C rating and lubricant film.
• The split outer ring of SL0149 is joined by retaining rings for handling only; never use those rings as a thrust face in the design.
